Abstract

The invention relates to a method for detecting water inlet noise of a toilet water tank. The method for detecting the water inlet noise comprises the steps of sample installation and debugging, determination of a sound source reference body and parallelepiped and hemisphere measurement surface, impulse noise determination, sound pressure level measurement, effective perceived noise level calculation and background noise and test environment correction and result evaluation. The method is characterized in that the impulse noise index is calculated to judge the water inlet noise impulsiveness,and A-weighted impulse sound level time weighting characteristic of the sound level meter is applied to accurately and quantitatively detect the water inlet noise characterized by the effective perceived noise level L<EPN> on the parallelepiped or hemispherical measurement surface. The method determines the maximum A-weighted impulse sound pressure level L'<pAi(ST)(max)> of the water inlet noise on the parallelepiped or hemisphere measuring surface, the effective sensory noise level L<EPN> in the specific water replenishing period is calculated, and a basis for evaluation of results is provided. The method fills the gap in the technical field of water inlet noise detection of the toilet water tank, and can provide detection technical support for improving product quality and standardizingmarket order.

Description

technical field [0001] The invention relates to a noise quantitative testing method, in particular to an A-weighted pulse sound level time-weighted characteristic "I" of a sound level meter to measure the noise level L effectively on a parallelepiped or hemisphere. EPN The invention discloses a method for detecting water inlet noise of a water tank inlet valve of a characterized toilet tank, and belongs to the technical field of physical and chemical performance detection of toilet tank accessories. Background technique [0002] In recent years, as a basic livelihood issue and an important window of civilization, the construction quality of toilets cannot be ignored. With the increasing use of toilets and water tank accessories in key areas of livelihood such as catering, tourism, and home, and the enhancement of people's awareness of health and environmental protection , The noise monitoring and prevention and control of toilet water tank water intake are increasingly conce...
